Make sure you have position on him. If you don't, leave the table. Pay attention to implied odds, but also re-raise him with a wider range than usual... maybe 99+, AQo+, AJs+, KQs and the occasional suited connectors. If he calls, c-bet the flop. You'll scoop a lot of nice pots this way. After you've done it a couple of times, tighten your range a little b/c he'll be more likely to look you up. If he puts up any resistance post-flop you'll have to make a tough decision, but look at his WTSD% and pay attention to what he shows down to figure out if he's as loose post-flop as he is pre-flop.
